Description

The THS3091 and THS3095 are high-voltage, low-distortion, high-speed, current-feedback
amplifier designed to operate over a wide supply range of ±5 V to ±15 V for applications requiring
large, linear output signals such as Pin, Power FET, and VDSL line drivers.

The THS3095 features a power-down pin (PD) that puts the amplifier
in low power standby mode, and lowers the quiescent current from 9.5 mA to 500 µA.

The wide supply range combined with total harmonic distortion as low as –69 dBc at 10
MHz, in addition, to the high slew rate of 7300 V/µs makes the THS309x ideally suited for
high-voltage arbitrary waveform driver applications. Moreover, having the ability to handle large
voltage swings driving into high-resistance and high-capacitance loads while maintaining good
settling time performance makes the devices ideal for Pin driver and Power FET driver
applications.

The THS3091 and THS3095 are offered in an 8-pin SOIC (D), and the 8-pin SOIC (DDA)
packages with PowerPAD™.
